These little beauties have "popped" up all over my yard (Brinnon, WA). I assume they were planted by a previous owner. They seem to do very well in full-sun, partial-shade, shade, good soil, poor soil. I am currently moving them all to one designated area for better "effect" and also because it breaks my heart to mow over them (and there are far too many to mow around). The ones I've moved so far seem to be doing well. Mine average about 6" tall. The blooms are beautiful and the foliage is unique. A lovely addition to any landscape.

This bulb is fairly new to me, but came up with the deepest shades of blue and purple. Lovely. Easy to plant and requires no maintenance. Stunning colors.
